Novel Defoamer for Glossy Water-Based Paints

Can you effectively prevent or destroy foams and not introduce noticeable surface defects in the finished coating of glossy paints?

What's the open innovation challenge?

Defoamers are necessary additives to paints in order to curtail the development of unwanted foams. However, while defoamers can effectively inhibit or destroy foams they may also leave undesirable surface defects. Although defoamers are applicable to matte and low-gloss paints with medium and high pigment volume concentrations (PVC) they are not suitable for glossy coatings which have low PVC. This is because they introduce noticeable surface defects and thus affect the glossy finish.

Therefore, the challenge is to look for a novel defoamer formulation or technology for use in water-based paints with low pigment volume concentration (PVC). The solution must be able to effectively prevent or destroy foams and not introduce noticeable surface defects in the finished coating.

This $25,000 challenge requires written documentation, experimental proof-of-concept data, and sample delivery if requested. The award depends upon the theoretical evaluation and experimental validation of your solution.
